-toniacomb. form
Primary stress is attracted to the first syllable of this combining form and vowels may be reduced accordingly.
Origin: A borrowing from Latin. Etymon: Latin -tonia.
Etymology: < scientific Latin -tonia (in e.g. dystonia dystonia n.) < ancient Greek -τονία (in ἀτονία atony n.) < τόνος tone n. + -ία -ia suffix1.Compare French -tonie , German -tonie . With the form -tony compare -y suffix3. F. Swediaur ( Novum nosologiae methodicae systema (1812) II. 71) uses the scientific Latin terms dystonia and hypertonia , modelled on the Greek forms ἀτονία atony n. and εὐτονία tension. The Greek forms δυστονία and ὑπερτονία cited by Swediaur are apparently not attested. French hypertonie is attested slightly earlier, in 1803. The form -tony is more widely used to form compounds with senses relating to sound or tone, e.g. homotony n. at homo- comb. form 1.
